What are the Correct Modifiers for CPT Code 20975 for Electrical Stimulation to Aid Bone Healing, Invasive?
Medical coding is a crucial aspect of healthcare, ensuring accurate billing and reimbursement for services provided. When it comes to musculoskeletal procedures, coding precision is particularly important. One such procedure is electrical stimulation to aid bone healing, invasive, coded as CPT 20975. Understanding the appropriate modifiers to use with this code is essential for accurate reporting. This article will explore the nuances of CPT code 20975 and its modifiers.
Let's dive into a story about a patient named John, who had an unfortunate accident that resulted in a fractured femur. John was admitted to the hospital where a renowned orthopedic surgeon, Dr. Smith, examined him.
Dr. Smith diagnosed a displaced fracture and determined that surgical intervention was necessary. The doctor suggested electrical stimulation therapy, which could accelerate bone healing. John agreed and consented to the procedure.
CPT Code 20975 for Electrical Stimulation to Aid Bone Healing, Invasive
Dr. Smith performed the procedure using an invasive technique. He made a small incision, carefully inserted an electrode, and connected it to an external power supply, initiating electrical pulses that targeted the fracture site to promote bone healing.
As a medical coder, it is our responsibility to accurately code this procedure, which would require reporting CPT code 20975 "Electrical stimulation to aid bone healing, invasive (operative)". However, sometimes a simple code may not accurately capture all aspects of a procedure. That's where modifiers come in. They allow coders to add specificity and detail to a code, providing more information to the billing department and insurers.
In the case of John, while CPT 20975 would be the correct code, we also need to consider the type of anesthesia HE was administered. If John's procedure was performed under general anesthesia, we must use Modifier 47 - Anesthesia by Surgeon. This modifier signifies that the surgeon was also the one who administered the anesthesia. However, we may not know whether the surgeon administered anesthesia without asking him or seeing him performing that task or accessing the procedure documentation. We need to always make sure that information on how the procedure was performed is gathered first! For example, when coder calls the provider or talks with them face to face to obtain this information.
Modifier 47: Anesthesia by Surgeon
Modifier 47 indicates that the surgeon who performed the procedure also administered the anesthesia. Now, you might be wondering, "How often does this happen?" Well, it's more common in some specialties like orthopedics and neurosurgery, where the surgeon may be trained in anesthesia.
Let's GO back to John's case. You, as a medical coder, were responsible for documenting his treatment. You already know the procedure was CPT code 20975 and it's highly likely that it was administered under general anesthesia because it is an invasive surgical procedure. Now, it's important to ascertain whether the surgeon also administered the anesthesia, which would be essential for proper coding. The first thing to check is the patient’s medical record for this information. Did the surgeon document the administration of the anesthetic? What does the anesthesiologist’s record say? By carefully checking the documentation, we're able to gain insight into who administered the anesthesia, and what code we should use.
The procedure record might say something like: "Procedure performed under general anesthesia administered by the surgeon, Dr. Smith." This statement clearly shows that Dr. Smith, the surgeon, administered the anesthesia. Now we can use Modifier 47 for CPT 20975 to provide detailed information about this specific procedure performed by Dr. Smith.
Another interesting example is Sarah. Imagine Sarah’s doctor is also a skilled anesthesiologist, and she had her knee arthroscopy done with general anesthesia administered by her surgeon. However, sometimes a provider might work with a separate anesthesia team. The patient record might note that the procedure was performed under general anesthesia administered by "a certified registered nurse anesthetist (CRNA) under the supervision of Dr. Jones." This indicates that the surgeon did not administer anesthesia. In this instance, we can skip Modifier 47 and don't need to add it in coding because the surgeon was not administering the anesthesia in this case. If we still find it useful, we can choose to add Modifier 52 - Reduced Services because it indicates that only part of the procedure is performed.
Modifier 52: Reduced Services
Let’s say Dr. Smith had already successfully performed electrical stimulation to aid bone healing on one femur of John. For another reason (that may be due to a second accident or surgery) John needed the same procedure done on the opposite femur. In this case, we might think about reporting only half the fee by using Modifier 52 - Reduced Services. We would use it if only part of the procedure (e.g., a procedure performed on one side, not on the other) was performed, because CPT code 20975 is designed for both sides.
Now, imagine that a different provider wanted to perform John's other procedure, but during the process, it was clear to the doctor that John could not handle the stress of the procedure. For whatever medical reason, the doctor chose to discontinue the procedure before it was completely finished. In this scenario, we would add Modifier 53 - Discontinued Procedure.
Modifier 53: Discontinued Procedure
Modifier 53 is a common modifier used for cases where the procedure is discontinued before completion. As a medical coder, this modifier might be very useful in documenting why the provider discontinued the procedure. You would then explain why the procedure was discontinued by writing your reasoning in the patient’s chart or medical records.
It could be something as simple as the patient expressing severe pain, to more serious scenarios, where the patient might suffer from a complication, like a drug reaction. In such a case, the patient’s chart could describe why the procedure had to be discontinued for their safety. Now that the procedure was not completely finished, we should always check with the provider on whether they are planning to continue the procedure later. If so, what code should be used? Will it be the same code as CPT 20975 or a different code for continuation?
The Importance of Staying Updated with CPT Code Changes and Guidelines
It's essential to keep UP to date on CPT codes, guidelines, and changes. As a medical coder, it is our duty to make sure that we always comply with all legal requirements. CPT codes are owned and published by the American Medical Association (AMA), and using them without proper licensing can result in severe legal penalties, including fines and even criminal charges. For this reason, it is imperative for all coders to pay the license fee and abide by all AMA regulations.
Understanding modifiers for CPT code 20975 is critical for accurate coding in musculoskeletal procedures, which ultimately benefits both healthcare providers and patients by facilitating timely and accurate reimbursement.
This article is a simplified example provided by an expert, but CPT codes are proprietary to the American Medical Association and medical coders should always refer to the latest AMA CPT manual for the correct information. Remember that you must purchase a license from AMA to legally use these codes in practice.
